new zealand

'overseas destination' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps you can see an association between them that I don't see?

'unfamiliar enthusiasm with' is the wordplay.
'unfamiliar' becomes 'new' (I've seen this in other clues).
'enthusiasm' becomes 'zeal' (zeal is a kind of enthusiasm).
'with' becomes 'and'.
'new'+'zeal'+'and'='NEW ZEALAND'

Can you help me to learn more?

(Other definitions for new zealand that I've seen before include "Antipodean country" , "Commonwealth country" , "where 28/25 [PINOT NOIR] is produced" , "Land of the kiwi" , "[TEST TEAM]" .)
